Gridfinity Bin with Printable Label by Pred (parametric) with extra Margins

This model is based on the fantastic Gridfinity Bin with Printable Label by Pred.  This has quickly become my go-to bin for organizing my hardware.  

I found that these print great on a modern printer.  On an older printer that is not as precise, and without Pressure Advance, I had some trouble fitting the labels correctly.  The original design had hard-coded dimensions for the slot.  I made this remix to add parameters to control some of the critical dimensions.

• Rounded corners (due to lack of Pressure Advance) on the label slot can prevent the labels from fitting properly.  To address this, I added a chamfer to the inside corners of the label slot, reducing the effect of rounded corners.
• The slot has a pretty tight tolerance.  To provide a bit of margin for less well-calibrated printers, I added some offset to the faces of the label slot.  By default, I added 0.25mm margins, and the labels are still held in place tightly.
• I printed some of these on a printer with a 0.8mm nozzle, and the biggest problem I found was that the supports for the label shelf did not print well.  They are 0.9mm by default, and the slicer made them a single line width.  I added a parameter to control the line width.  Printing a 1.5mm width caused the slicer to use two lines, which prints much more reliably.
• The original design has a parameter for the bin Height.  I found that when the height is 3 units or below, the geometry breaks by extruding the back of the label shelf support outside the body of the bin.  To prevent this, I added a calculation to cap the minimum height at 3.01 units (no matter what you set it to), which generates correctly.

Thanks to Eistee who graciously provided a Python script to generate labels
https://www.printables.com/model/676564-gridfinity-bin-labels-hexagon-socket-head-cap-scre
which I adapted to be able to generate bins in a variety of sizes.  I used the information on their model page to learn how to set up scripting in Fusion 360.  It was not as intimidating as I expected.

I set the label slot margins to 0.25mm, left the shelf support at 0.9mm, and generated bins at every size from 1x1 to 5x5, with every combination of Divisions from 1 to 2x the width.  I used heights 3, 4.5, and 6 units tall.  If anyone needs larger or taller bins, it's pretty easy to modify the script to generate them all.
